From Kate Middleton's early time in the public eye, during which she embraced preppy puffer jackets and hiking boots, to more refined gowns at evening galas, the royal’s wardrobe has experienced a coming of age over the years, prompting her sartorial status to soar.
Most recently, the royal stunned fans when she arrived at the No Time To Die premiere wearing a shimmering gold Jenny Packham gown, complete with a sheer cape and structured shoulders.
Her appearance was praised on social media, with some describing it as “the best she’s ever looked”, while other said it was “the biggest wow red carpet moment” of the last two years.
Today, as she rings in her 40th year, the Duchess is recognised for her effortless polish – there isn’t a public appearance where she doesn’t look perfectly put together – with the so-called “Kate effect” causing websites to sell out of designs in minutes, months-long waiting lists and surges in sales for lesser-known brands.
While the royal regularly wears items from a number of luxury fashion designers, including Emilia Wickstead and Erdem, no brand is held in as high regard by Kate as Alexander McQueen, which she chose to create her custom wedding gown in 2011.
In the years that have followed, Kate has turned to the luxury brand on several occasions for appearances including the Queen’s birthday party, the Royal Variety Performance and Trooping the Colour.
However, the Duchess regularly ensures that such royal pageantry is balanced by wearing fashion that’s considered to be more “down-to-earth”, with budget-friendly pieces from high street favourites such as Zara, Hobbs and LK Bennett.
Aside from the royal wedding, some of Kate’s most talked-about fashion statements have been made on the steps at the Lindo Wing of St Mary’s Hospital in Paddington, following the births of each of her children, George, Charlotte and Louis.
The Duchess introduced all three newborns to the world with a bedside blowdry and perfectly put-together looks designed by Jenny Packham in variations of spring yellow, baby blue and scarlet red.
Here are Kate’s most memorable fashion moments.
